Note• Make sure that the import source or unit is in standby mode.• The import source or unit must be specified at the time of import/export. The imported data is addedto the existing phonebook data.– If the existing phonebook data has an entry with the same record ID as an imported entry, the entryis overwritten with the imported entry.– If the existing phonebook data has an entry with no record ID, it will be left in the phonebook.– If the imported phonebook data has an entry with no record ID, the imported entry is added as anew entry unless an existing entry with the same name and phone number is found.Phonebook entries that are added via the unit are not assigned record IDs. Therefore, it isrecommended to export phonebook data from the unit, assign record IDs manually and then re-importthem. Doing so can help manage phonebook data.• The phonebook for a unit has the following limitations:– A maximum of 1,000 phonebook entries can be stored in the unit. If the unit already has phonebookdata, it accepts up to the 1,000th entry, including the existing entries. The rest of the entries willnot be imported, and the message "Phonebook entries reach max count, the exceeded entry maynot import to phone" is displayed on the web user interface.– The name can contain up to 24 characters.– The phone number can contain up to 32 digits.– Phonebook entries exceeding the characters or digits limits cannot be imported properly.– "Invalid file format" is displayed on web user interface if the imported file is not CSV file, or if thereis a syntax error.• If the export is interrupted by an operation on the unit, only the data that has been successfully exportedbefore the interruption is exported to a file.6.2 Dial PlanThe dial plan settings control how numbers dialed by the user are transmitted over the network.
